Shakespeare Adds To Resistat® Family, Introduces IsoTuff

Columbia, S.C.-based Shakespeare Conductive Fibers LLC has added type F902 to its family of
Resistat® fibers for electrostatic discharge control. When compared to the standard type F901
fiber, type F902 fiber has less than half the coefficient of friction, according to the company.

Shakespeare creates the fiber using a process called suffusion, which permanently bonds
electrically conductive carbon particles to a nylon base fiber, resulting in a fiber with improved
surface smoothness. The fiber is suitable for use in a wide range of processes in which static
electricity control is critical, including textile, nonwovens and wet-laid applications.

Shakespeare also has introduced IsoTuff man-made monofilaments produced using a patented
process that alters the surface properties of a semi-crystalline polymer. According to the company,
this surface enhancement provides the fiber with increased toughness, improved wear resistance and
reduced susceptibility to fracture.

The IsoTuff technology can be used to enhance a variety of thermoplastic materials including
nylon, polypropylene, polyester and nylon copolymers. End-uses include industrial belts, conveyors
and paper machine clothing.
